CHAPTER 1: AC POWER MEASUREMENT
CHAPTER 1
AC POWER MEASUREMENT
The economics of electric power distribution networking dictate several configurations of AC power
transmission. The number of phases and voltage levels characterize these configurations.
1.1: Single Phase System
A single phase system is a basic two-wire system used in low power distribution applications, such as
residential communities or offices. Typically, the voltage is 120V AC. For higher power requirements,
such as small commercial facilities, the typical power configuration is two lines of 120V AC opposite in
phase (see Figure 1.1 B, below).
This system produces 120 volts from line to neutral for lighting and small appliance use. The line-to-line
voltage is 240V AC, used for higher loads such as water heaters, electric dryers, ranges and machinery.

Figure 1.1: Single Phase System: (A) Two-Wire, (B) Three-Wire
The power (W) in a single phase system is: W = E • I • cosΘ
E = potential, I = current, and cosΘ = phase difference between the potential and the current.
Power in a 120/240V AC system is: W = (ELine 1 • ILine 1 • cosΘ) + (ELine 2 • ILine 2 • cosΘ)
Phase differential between the potential and the current results from a non-resistive load, either reactive
or capacitive.
Reactive power (VAR): The additional power consumed that does not produce any work but must be
delivered to the load: VAR = E ⋅ I ⋅ sinΘ . This is a measure of the inefficiency of the electrical system.
Apparent power (VA): The total power delivered to the load, and the vector sum of real power and
reactive power.
Power Factor (PF): The ratio between real power and apparent power: PF =

Figure 1.2: Relationship between apparent, real
and reactive power
Ideal power distribution should have a PF of 1. This condition can be met only if no reactive power
loads exist. In real life applications, many loads are inductive loads. Often, corrective capacitors are
installed to correct Poor Power Factor (see Section 1.3).
1.2: Three-Phase System
A three-phase system delivers higher levels of power for industrial and commercial applications; the
three phases correspond to three potential lines. A 120° phase shift exists between the three potential
lines.
A typical configuration has either a Delta connection or a Wye connection (see Figure 1.3, below).
In a three-phase system, the voltage levels between the phases and the neutral are uniform and defined

CHAPTER 1: AC POWER MEASUREMENT
Voltages between the phases vary depending on loading factors and the quality of distribution
transformers. The three-phase system is distributed in different voltage levels: 208V AC, 480V AC, 2400V
AC, 4160V AC, 6900V AC, 13800V AC, and so on.
Power measurement in a poly phase system is governed by Blondel's Theorem. Blondel’s Theorem
states that in a power distribution network which has N conductors, the number of measurement elements
required to determine power is N-1. A typical configuration of poly phase system has either a Delta
connection or a Wye connection (see Figure 1.4, below).

1.3: Consumption, Demand and Poor Power Factor
W = instantaneous power T = time in hours
CONSUMPTION: WH = W × T
The total electric energy usage over a time period is the consumption of WH.
Typically, the unit in which consumption is specified is the kilowatt-hour (KWH): one thousand watts
consumed over one hour. Utilities use the WH equation to determine the overall consumption in a billing
period.
DEMAND: Average energy consumed over a specified time interval. The utility determines the interval,
typically 15 or 30 minutes. The utility measures the maximum demand over a billing period. This
measurement exhibits a deviation from average consumption, causing the utility to provide generating
capacity to satisfy a high maximum consumption demand. The highest average demand is retained in the
metering system until the demand level is reset.
POOR POWER FACTOR: Results in reactive power consumption. Transferring reactive power over a
distribution network causes energy loss. To force consumers to correct their Power Factor, utilities
monitor reactive power consumption and penalize the user for Poor Power Factor.

CHAPTER 1: AC POWER MEASUREMENT
1.4: Waveform and Harmonics
Ideal power distribution has sinusoidal waveforms on voltages and currents. In real-life applications,
where inverters, computers, and motor controls are used, distorted waveforms are generated. These
distortions consist of harmonics of the fundamental frequency.
SINUSOIDAL WAVEFORM: A • sin ( ω ⋅ t)
DISTORTED WAVEFORM: A • sin(ω • t) + A 1 • sin(ω1 • t) + A 2 • sin( ω 2 • t) + A 3 • sin( ω3 • t) + L
TOTAL HARMONIC DISTORTION (THD):
% of THD =
RMS of Total Harmonic Distortion Signal
× 100
RMS of the Fundamenta l Signal
HARMONIC DISTORTION: A destructive force in power distribution systems. It creates safety problems,
shortens the life span of distribution transformers, and interferes with the operation of electronic devices.
The Futura+ monitors the harmonic distortion to the 31st harmonic. A waveform capture of distorted
waveform is also available.

CHAPTER 3
ELECTRICAL INSTALLATION
3.1: Connecting the Current Circuit
Install the wiring for the current at 600V AC insulation as a minimum. The cable connector should be
rated for 6 Amps or greater and have a cross-sectional area of 16 AWG minimum.
Mount the current transformers (CTs) as close as possible to the meter for best accuracy. The following
table illustrates the maximum recommended distances for various CT sizes, assuming the connection is
via 16 AWG cable.

Table 3.1: CT Size and Maximum Distance
WARNING:
DO NOT leave secondary of the CT open when primary current is flowing. This causes high voltage that
will overheat the secondary of the CT. Use a shorting block on the secondary of the CT.
3.2: CT Connection
If the meter is connected directly to the current (up to 10 Amps max.), maintain the exact connection to
avoid incorrect polarity.
When the meter is connected using the CTs, you must maintain the correct CT polarities. CT polarities
are dependent upon correct connections of CT leads, and upon the direction the CTs are facing when
clamped around conductors. The dot on the CT must face the line side; the corresponding secondary
connection must connect to the appropriate input on the meter. Failure to connect CTs properly results in
inaccurate power readings. If your meter is not reading power properly, it is more than likely the CT is
incorrectly wired.
Note: CTs are shorted if connected to the terminal block model DSP2 or 3 even if it is detached
from the meter.
HELPFUL DEBUGGING TOOLS
OPTION 1: ISOLATING A CT CONNECTION REVERSAL POWER READING
If your meter does not read the correct watts after installation, it almost always means that the CT’s have
been wired in the wrong polarity. To check the polarity of the CT after the monitor has been installed, look
at the single phase WATT readings to see that each of the readings are positive (assuming you are
consuming power). If one of the WATT readings is negative, that particular phase CT is reversed.
To check the single phase WATT reading, press the Power button twice while the annunciator is
positioned to WATTS. Then press the Phase/Next button to cycle through the phases. After connecting
the polarity of the CTs, the WATT and VAR readings should be correct.

CHAPTER 3: ELECTRICAL INSTALLATION
OPTION 2: ISOLATING A CT CONNECTION REVERSAL USING VOLTAGE READINGS
!
!
Remove potential connections to terminals 6 and 7. Observe the KW reading. It should
be positive.
If negative, reverse the CT wires on terminals 8 and 9.
Connect terminal number 6 potential. If KW decreases to about zero, reverse CT wires on
terminals 10 and 11.
Connect terminal number 7 potential. If KW is one-third of expected reading, reverse CT wires to
terminals 12 and 13.
3.3: Connecting the Voltage Circuit
For proper meter operation, the voltage connection must be maintained. The voltage must correspond to
the correct terminal.
The cable required to terminate the voltage sense circuit should have an insulation rating greater than 600V AC and a
current rating greater than 0.1 A.
3.4: Selecting the Voltage Fuses
We strongly recommend using fuses on each of the sense voltages and the control power, although
connection diagrams do not show them. Use a 1 Amp fuse on each voltage input.
The meter can handle a maximum voltage of 150V phase to neutral. PTs are required for higher
voltages. Suffix -G extends the maximum direct voltage to 300V phase to neutral, 600 volt phase to
phase.
3.5: Connection to the Main Power Supply
The meter requires separate control power to operate. Listed are the five different power supply options
and corresponding suffixes.

Note: For DC-powered units, polarity should be observed. Connect the negative terminal to L and
positive terminal to L1. An earth ground connection to chassis is mandatory for normal
operation (terminal three). Do not ground the unit through the negative of the DC supply.
Note: Externally fuse power supply with a slow-blow 3 Amp fuse.
3.6: Electrical Connection Installation
Choose the diagram that best suits your application and maintain the CT polarity. Follow the outlined
procedure to verify correct connection. IMPORTANT: For PT connections only, short terminals 3 and 4.
Connect local ground to terminal 3. This protects the unit from spikes and transients.

CHAPTER 3: ELECTRICAL INSTALLATION
• The meter and terminal module DSP3 are factory calibrated together; the serial numbers are matched
on both. The DSP3 input module and the meter base MUST MATCH!
• Mismatching of the meter and DSP3 input module will cause inaccurate readings because calibration
ratios are stored in the meter’s memory, not in the DSP3 input module.

3.7: Relay, Protection and Pulse Output
(This section applies only to the -NL or -NL2 Relay Option.)
EPM 5300P RELAY OVERVIEW
The EPM 5300P offers dry contact relay output capability. The EPM 5200P only offers KYZ pulse outputs and cannot
be configured to trip contacts on events.
FAIL-SAFE MODE: The EPM 5300P -NL option gives the user an adjustable tripping bandwidth. The
user specifies a range over which functions, such as frequency, phase relation and voltage, are
acceptable. The relay releases during times of normal operation, and engages when functions are
outside specified normal levels. The relay can be programmed to engage during normal operating
conditions, and release outside specified normal range (particularly when power is lost). This is the
fail-safe mode.
HYSTERISIS: The EPM 5300P -NL option also includes adjustable hysterisis. In addition to a time
delay on activating any contact, the user may specify a lower level to release the relay, rather than
releasing after the initial alarm point. This is ideal during load shedding when an alarm activates at a
certain level and the user does not want to turn off the alarm until a much lower, safer level.
SETABLE DELAYS: After reaching the alarm point, a change in relay status may be delayed for 255
seconds. The user also has the option of allowing the device to change relay status without any delay.
After the alarm condition passes, the relay can be stopped from returning to a normal condition for a
programmable time. Each delay time is independent of one another.
AND/OR LOGIC: If several parameters are assigned to one relay, the user can trip the relay if all
functions are out of limit (and programming), or if one function is out of limit (or programming). For
example, if limits on Voltage, Kilowatts, and Phase Imbalance are programmed and tied to Relay 1, the
user can either trip the relay if one function is out of limit, or if all functions are out of limit.
2 RELAYS & 1 KYZ PULSE OUTPUT -NL OPTION
The EPM 5300P's flexibility accesses a variety of relay options through the Programming Mode (see
programming sections). The relay option package consists of three relays: two can be dedicated to alarm
or controlled through communication (or both) and one for KYZ pulse output.
If the relays are controlled through communication, there are two different modes:
" Lock ON
" Lock OFF
Relay will not be affected by any alarm condition.
Relay will not be affected by any alarm condition.
If the relays are used for communication and alarm, there are four different modes:

Relay stays on regardless of any alarm condition.
Relay stays off regardless of any alarm condition.
Relay turns on unless other conditions force it off.

4.2: RS-485
Each EPM 5300P or 5200P instrument has a unique address up to four digits long. This allows the user
to communicate with up to 10,000 instruments. Available standard baud rates are 1200, 2400, 4800, and
9600. To select the proper baud rate, apply the following rules:
The unit operates up to 9600 baud. For a smaller number of instruments over a long distance, use a
lower baud rate. Optimal recommended baud rate is 1200 baud, if noisy conditions exist.

CHAPTER 4: COMMUNICATION INSTALLATION
YOU MAY WANT TO USE A MODEM MANAGER RS485-RS232 CONVERTER
When speaking to most RS-485 or RS-232C based devices, the remote modem must be programmed for
the communication to work. This task is often quite complicated because modems are quirky when talking
to remote devices. To make this task easier, EIG has designed a Modem Manager RS-485 to RS-232C
converter. This device automatically programs the modem to the proper configuration. Also, if you have
poor telephone lines, modem manager acts as a line buffer, making the communication more reliable.

CHAPTER 5: OVERVIEW
5.5: Accessing Max/Min Values
Max/min values represent the highest and lowest average demand over a user programmable time period
known as the Integration Interval. The readings are calculated using a rolling average technique. Each
second, a new reading is used to calculate the max/min; the last reading of the interval is dropped off.
The highest max during an averaging period is stored until the user resets the max/min. This is similar to
amp demand meters. It is commonly referred to as Thermal Demand.
To access a max/min value while displaying a desired measurement, press MAX/MIN/LIMITS—once for
the max value; twice for the min. Examples given below are for voltage and current phases. Use the
same procedure for all other parameters.

of any abnormal conditions. Each limit detects readings either above or below a set level. The EPM
5200P does not have this feature.
SET LIMITS: Point when the relay changes position, if the EPM 5300P is equipped with the Relay Option
(Suffix -NL).
If a limit is exceeded, only the annunciator for LM1 and/or LM2 flash.
To view the setup of the LM1/LM2 set limits:
•

5.9: Voltage Phase Reversal and Imbalance
In a three-phase power distribution system, normal phase shift between each line is 120°. If the EPM
5300P detects an abnormality, it displays a message of PH. The EPM 5200P does not have this feature.
VOLTAGE PHASE REVERSAL: If there is an incorrect connection, such as mistaking line A for line B, a
PH message appears. The correct sequence is a-b-c.
VOLTAGE PHASE IMBALANCE LIMIT: This is detected using the phase imbalance limit in the
Programming Mode. The phase imbalance is expressed as a percentage, with 0% indicating a 120°
phase shift between each line. A PH message appears if the limit is exceeded.

CHAPTER 8
ENTERING PROGRAMMING MODE
8.1: Checksum Error—Protective Self-Checking Algorithms
This checksum error is a protective self-checking wealth algorithm designed to alert the user when a
procedure has not been correctly followed, ensuring that the meter does not display inaccurate readings.
If the control power is interrupted while in Programming Mode or the user does not completely exit, the
meter enters a checksum mode. The max LED flashes. Press AMPS and PHASE/NEXT simultaneously
and the unit recovers. Follow the procedure to enter Programming Mode to check program data. If the
data is correct, then exit.
8.2: Password Entry
The EPM 5300P and 5200P are password protected. To enter the Programming Mode, key in the
following password: 555.
The password entry may seem awkward at first. It is designed to be difficult to use initially. This secures
unauthorized tampering. After you become familiar with password entry, you will find it quick and easy to
accomplish.
NOTE: The meter will not store any programming unless properly exited (see Chapter 14 to Exit).

CHAPTER 9: PROGRAMMING GROUP 0 – GLOBAL METER SETUP
OPEN DELTA SYSTEM INSTALLATION PROGRAMMING
A special switch is used to indicate that the electrical system being monitored is a Three-phase WYE or
Three-Wire Open Delta System using the connection installation (see Chapter 3). The switch is located in
GROUP 0, FUNCTION 3, Pack 1, Switch D.
WARNING: This switch should be set to UP only if the electrical system is a Three-Wire Delta or Open
Delta, using 2 PTs. Otherwise, the switch should be set to DOWN. Failure to select this switch results in
Phase-to-Neutral readings, as well as incorrect power readings, with the 2PT connection.
Special Open Delta Connection Installation should be followed in the Installation and Operation section
(Chapter 3).

NOTE: When programming for MODBUS protocol configuration of LIPA (Long Island Power Authority)
mapping options may be performed through communication.
9.5 Modbus Plus Capability
When using the MPI Modbus Plus adapter, the meter values should be set to speak to Modbus RTU with
a meter address of 0001 and a baud rate of 9600 baud. The Modbus Plus address is programmed into
the MP1 Modbus Plus adapter directly.
PRINTING OPTION
To print, access Mode 1 and Mode 2 (see Part I: Installation and Operation). Printing serial options should
be disabled when using a multimeter communications connection RS485.
DISABLING PREVENTS:
1. Printing through the keypad.
2. Corrupting data at a computer terminal while multiple meters poll.
3. Corrupting printing commands through communications.
This option connects a serial printer to the RS232 port and prints the data. Disable this feature when the
meter is not using an RS232 port (i.e., when RS485 or DC outputs are being used).

CHAPTER 9: PROGRAMMING GROUP 0 – GLOBAL METER SETUP
9.8: Group 0, Functions 4–5—Time Delay for Relays 1 and 2 (Option – NL)
GROUP 0, FUNCTIONS 4–5 sets the time delay for Relays 1 and 2 between 0 and 255 seconds. This
allows conditions (example below) to exist for a user-specified time period before the relay or alarm
activates. If a time greater than 255 seconds is entered, the meter defaults to the maximum value of 255
seconds.
Example: If Relay 1 is set for 300 amps and the amps increase to 301, the Relay trips only after a
programmed delay period. If the meter then measures 299 Amps, the Relay returns to its original position,
after the programmed delay.

CHAPTER 10
PROGRAMMING GROUP 1 – VOLTAGE, AMP AND WATT SCALE
SETTINGS
NOTE: The EPM 5300P and 5200P full scales will already be programmed if the order specified current
and voltage transformer ratios. The meter label indicates any full scale setup.
Programming Group 1 contains voltage, amperage and full scale power selection, along with scale factor
selection and decimal point placement.
The user can re-scale without removing the EPM 5300P for calibration. The 5300P has been calibrated at
standard levels in GROUP 2. Mathematically convert any full scale ratios to those calibrated levels. If a
different current or voltage transformer is used, program the primary value of its ratio. If necessary,
convert the ratio to a secondary value of five amps standard current (1 amp is a special order) and 120V
or 75V nominal voltage (options L only).
FORMULAS:
Primary
Secondary
Primary
Secondary
x 120V
x 75V
Primary
Secondary
x 5A
It may be necessary to convert the full scale to a larger unit. There is a resolution limitation for all full
scales of 2000. If a display reading exceeds 2000, it may be unstable and subject to zeroing problems.
Example: The full scale for a CT ratio of 3000/5 should be 03.00 kA.
When changing a PT or CT full scale, calculate the new watts full scale and make any necessary
changes. The watts full scale will not auto range.

NOTE: Shift the decimal left to increase resolution. Wattage should not exceed a numeral value of 2500.
Shift the decimal one position right to decrease resolution.
GE Multilin
EPM 5000 series Advanced Power Meters
63
CHAPTER 10: PROGRAMMING GROUP 1
Full Scale Wattage (FSW) is the product of FSV and FSA. For FSW for three phases multiply the FSW
per phase by 3.
Example 1:
Full Scale Voltage (FSV)=120 V
Full Scale Amperage (FSA)=5.00 A
FSW (one phase) =120 Vx5.00 A
FSW (one phase)=600 W
FSW (three phase)=600 Wx3 = 1,800 W
Here the FSW is too small a value for a Megawatt meter. FSW in the Kilowatt meter equals 1.800 KW. In
FUNCTION 2, four 9s appear. Place the decimal point after the first digit. The user cannot change the
four digits. The user can only move the decimal point placement.
Example 2: 480/120 PT, 1000/5 CT
FSV=480 V
FSA=1000 A
FSW (one phase)=480 V ⋅ 1000 A
FSW (one phase)=480,000 W
FSW (three phase)=480,000 W ⋅ 3 = 1,440,000 W
FSW for a Kilowatt meter equals 1440. KW. FSW for a Megawatt meter equals 1.440 MW. In FUNCTION
2 place the decimal point after the last digit for a Kilowatt meter and after the first digit for a Megawatt
meter. It is important to note which type of bezel labeling you have when making this decision.
Example 3: 14.4 KV/120, 1000/5 CT
FSV=14.40 KV
FSA=1000 A
FSW (one phase)=14,400 Vx1000 A
FSW (one phase)=14,400,000 W
FSW (three phase)=14,440, 000 Wx3 = 43,200,000 W
FSW for a Kilowatt meter equals 43,200 KW. Here the FSW is too large a value for a Kilowatt meter (the
range is 000–2500). FSW for a Megawatt meter equals 043.2 MW. In FUNCTION 2, place the decimal
after the third digit.
NOTE: In some applications where the load is normally very low, the watts resolution can be increased
by moving the decimal point one position left.

CHAPTER 11
PROGRAMMING GROUP 2—METER CALIBRATION
WARNING—READ THIS SECTION CAREFULLY BEFORE PROCEEDING:
•
Any rescaling, such as a change in a transformer ratio, can be accomplished in GROUP 1.
Calibration is not necessary.
•
Meter calibration cannot be performed if the meter is installed for service. The sensing inputs must be
connected to a power supply with variable voltage and separate current outputs.
•
The calibration procedure requires highly accurate and stable input signals. Incorrect readings result
from improper calibration procedures. If unsure, return unit to the factory for calibration.
•
BEFORE calibrating any channel, make a note of its Full Scale Setting (see Chapter 10). Set the Full
Scale in accordance with Table 10-2 for calibration. Restore original Full Scale Setting when
calibration is completed.
11.1: Calibration Requirements
Calibration on the EPM 5300P requires precise inputs of 120 Volts, 5 Amps, and 2.5 Amps. The EPM
5300P -G model requires precise inputs of 300 Volts, 5 Amps, and 2.5 Amps. If this equipment is
unavailable, contact us for assistance.

time (see Chp. 10).
12.2: Time Delays & Relay Mode
Time Delay indicates whether a delay exists in the relay changing position. Relay Mode indicates
whether the relay will act as a protective switch or not.
NOTE: The Time Delay and Relay Mode are both located in GROUP 0, FUNCTIONS 4 & 5.
THE FOLLOWING GROUPS ALLOW THE USER TO PROGRAM LIMITS AND RELAYS:
GROUP 4: VOLTS/AMPS SET LIMITS / RELAYS

PHASE REVERSAL AND PHASE IMBALANCE SET LIMITS/RELAYS
13.1: Phase Reversal and Phase Imbalance
The set limit alerts the user of an unbalanced or a reversed phase in a Three-phase System. The EPM
5300P has two options for this purpose. The standard set-up is clockwise ABC rotation.
Counterclockwise CBA rotation can be selected in GROUP 03.1, Switch C UP.
PHASE REVERSAL: Activates when a reversed phase enters the EPM 5300P’s metering system.
PERCENT PHASE IMBALANCE: Activates when the user's preset value percent phase imbalance is
exceeded. For example: an unbalanced Three-phase System.
Note: The EPM 5200P does not have this capability.

CHAPTER 16
ETHERNET OPTION
The EPM5350P, Meter with the Ethernet Option, has all the components of the standard Meter PLUS the
capability of connecting to multiple devices over Ethernet. The Meter face is the same as the EPM5300P
(except for the model number).
16.1: Ethernet Module
The Ethernet connection is made with a small module added to the back of the meter. This small but
powerful module has simply an RJ-45 Port and four Status LEDs.

16.2: Ethernet Option Setup
This chapter covers the required steps to get the Ethernet Interface on-line and working. There is only
one method used to log into the Ethernet Server and set up the IP address:
•
Network Port Login: make a Telnet connection to the network port (9999).
It is important to consider the following points before logging into and configuring the Ethernet Interface:
92
•
The Ethernet Interface’s IP address must be configured before a network connection is available.
•
Only one person at a time may be logged into the network port. This eliminates the possibility of
several people trying to configure the Ethernet Interface simultaneously.

CHAPTER 16: ETHERNET OPTION
16.3: Default IP Address
The Ethernet Interface ships with a default IP address set to 0.0.0.0, whish automatically enables DHCP
within the Ethernet Interface.
Provided a DHCP server exists on the network, it will supply the Ethernet Interface with an IP address,
gateway address and subnet mask when the Ethernet Interface boots up. If not DHCP server exists, the
Ethernet Interface will respond with a diagnostic error: the RED Diagnostic LED blinks continuously and
the GREEN Status LED blinks five times.
16.4: AutoIP
Auto IP allows an Ethernet Interface to obtain an address in a network that does not have a DHCP server.
(Windows 98 and 2000 also support AutoIP.)
AutoIP assigns a random valid address to the Ethernet Interface in the range of 169.254.x.1 to
169.254.x.1 (x can be between 0 and 255). This range of IP addresses is not to be used over the
Internet. If the Ethernet Interface has not been configured manually and cannot find a DHCP server, it
automatically chooses an address from the reserved range. The Ethernet Interface then uses the
Address Resolution Protocol (ARP) to send out a request asking if any node is using that address. If
another node is using the same address, the Ethernet Interface assigns another IP address, reboots and
repeats the sequence.
NOTE: AutoIP-enabled Ethernet Interfaces are constantly looking for DHCP servers. If a DHCP server
becomes available on the network, the AutoIP-enabled Ethernet Interface switches to the DHCP serverprovided address and the unit reboots. If the DHCP server exists but denies the Ethernet Interface an IP
address, the Ethernet Interface does not attach to the network, but waits and retries.
AutoIP allows a small network of AutoIP-enabled devices to be set up without any need for a DHCP
server or static IP addresses.
AutoIP can be disabled be setting the IP address to 0.0.1.0. The 1 in the third octet is the disabling
factor.
16.5: Setting the IP Address
The Ethernet Interface’s IP address must be configured before a network connection is available. If the
IP address was not set automatically via DHCP, set it now using a network and the setup (configuration)
menu.
NETWORK PORT LOGIN
The ARP method is available under UNIX and Windows-based systems. The Ethernet Interface will set
its address from the first directed TCP/IP packet it receives.
ARP ON UNIX
On a Unix host, create an entry in the host’s ARP table using the intended IP address and the hardware
address of the Ethernet Interface, which is found on the product label.
arp –s 191.12.3.77 00:20:4a:xx:xx:xx

CHAPTER 16: ETHERNET OPTION
ARP ON WINDOWS
In order for the ARP command to work on Windows, the RP table on the PC must have at least one IP
address defined other than its own. If the ARP table is empty, the command will return an error message.
Type ARP –A at the DOS command prompt to verify that there is at least one entry in the ARP table.
If the local machine is the only entry, ping another IP address on your network to build a new entry in the
ARP table; the IP address must be a host other than the machine on which you are working. Once there
is at least one additional entry in the ARP table, use the following command to ARP the IP address to the
Ethernet Interface:
arp –s 191.12.3.77 00-20-4a-xx-xx-xx
TELNET TO PORT 1
Now open a Telnet connection to Port 1. The connection will fail quickly (3 seconds). But the Ethernet
Interface will temporarily change its IP address to the one designated in this step.
telnet 191.12.3.77 1
TELNET TO PORT 9999
Finally, open a Telnet connection to port 9999 and set all required parameters.
telnet 191.12.3.77 9999
NOTE: This IP address is temporary and will revert to the default value when the Ethernet Interface’s
power is reset, unless you log into the Ethernet Interface and store the changes permanently.
16.6: Network Configuration
Certain parameters must be configured before the Ethernet Interface can function on a network. The
Ethernet Interface can be locally or remotely configured using the following procedures:
Use a Telnet connection to configure the unit over the network. The Ethernet Interface’s configuration is
stored in nonvolatile memory (NVRam) and is retained without power. The configuration can be changed
at any time. The Ethernet Interface performs a reset after the configuration has been changed and
stored.
As mentioned above, to configure the Ethernet Interface over the network, establish a Telnet connection
to port 9999. From the Windows Start menu, click Run and type the following command, where x.x.x.x is
the IP address and 9999 is the Ethernet Interface’s fixed network configuration port number.
telnet x.x.x.x 9999
NOTE: Be sure to include a space between the IP address and 9999.

After entering Setup Mode (confirm by pressing Enter), you an configure the parameters by entering one
of the numbers on the Change Setup Menu, or you can confirm default values by pressing Enter. Be
sure to store new configurations when you are finished. The Ethernet Interface will then perform a power
reset.

BAUD RATE
The Ethernet Interface and attached serial device (the meter) must agree on a speed or baud rate used
for the serial connection. Valid baud rates are 1200, 2400, 4800 and 9600 (default). For the EPM 5350P,
default settings are 9600 baud rate, 8 data, 1 stop, no parity, Modbus RTU.
